I would assume it has something to do with Side Assist being a much more available option. Maybe they couldn't run all the wiring and lights into the mirror without removing the motor to fold them. Just a thought...really wish my '09 A5 had them..oh well...Thanks Jimmyz. I think its just stupid to get rid of something like that!
I may be wrong... if you would like to try, www.OEMPL.us has a 4 way brushed chrome side mirror switch from an RS6 for 45 bucks.Thanks Jimmyz. I think its just stupid to get rid of something like that!
